INCNDESCENT VAPOR-BURNER.

SPECIFICATION' forming part of Letters Patent No. 748,342, dated.December 29, 1903. `Application led October 10, 1902l Serial No.126.700. (No model.)

.To all whom it may concern:

Be it known that I, GEORGE A. BONELLI, a citizen of the United States,and a resident of Kingman, in the county of lMohave and Territory ofArizona,ihave invented a new and Improved Incandescent Vapor-Burner, ofwhich the following is a full, clear, and exact description.

My invention relates to acombined hydrocarbon-gas generator and galleryand mantle support, and furtherv relates to an improved form `ofhydrocarbon-valve for use more particularly with the generator and tocertain details of construction hereinafter described.

My invention is used in `connection with burners for heating,illuminating, &c.

I will describe a combined hydrocarbon-y gas generator and gallery andmantle support embodying myinvention, and then point out the novelfeatures in the appended claims.

Reference is to be had to the accompanying drawings, forminga part ofthis specification, y

in which similar characters of reference indicate corresponding parts inall the figures.

Figure 1 is a front elevation, partly in section, showing my device inuse. Fig. 2 is a vertical section taken at right angles to Fig. 1. Fig.is a fragmentary section, somewhat enlarged, upon the line 3 3 of Fig. 1looking in the direction of the arrow. Fig. 4 is a detail section uponthe line 4 4 of Fig. 3, and Fig. 5 is a fragmentary section showing amodified form of the generatontube.

The hydrocarbon-pipe 1 is connected with a casing 2, which is providedwith the valve` stem 3, having a hand-wheel 4 and turning in astuffing-box 5 for operating the valve 6. The passage 7 (shown moreparticularly in Fig. 3) is connected with the valve 6 and is suppliedwith hydrocarbon liquid by the same. Another casing 8 is provided withcylindrical passages 9 and 10. Disposed within the pas sage l0 is a flatplate or needle 11, (shown more particularly in Figs. 3 and 4,)andmounted upon the screw-stem 12, so as to be revoluble by means of thehand-wheel13. The screw-stem 12 engages a stuffing-box 14, mounted upona threaded stem 15. A vaportube 16 is connected with the passages 7 andtwo casings 2 and 8, respectively, are screwed. as indicated in Fig. 3.

The vapor-tube and each of the other parts may be made of any suitablematerial. The casing 8 is provided with a lug 18, which engages anaperture 18a in the casing 2, thereby holding the two casings together;Upon a tubular support 19 is mounted a gallery 20, provided with a gauzescreen 20a, which is provided with holes 20h, through whichthe tubularsupport passes. A hollow mantle 21, provided with a central opening 22,is hung loosely upon the vaportube 16 in such a manner that the upperend of the tube 16 partially obstructs the opening 22 in the mantle. Thechimney-support 23 sustains the chimney 24 in the usual manner. A diskof gauze 25 may be placed in the tube 21 adjacent to the valve-casing 2.The lower ends of the vapor-tube 16 preferably engage packings 26,whereby the tube is rendered gastigbt, as indicated in Fig. 3.

In the structure shown in Fig. 5 the vaportube 162L is spiral, whereasin the other figures it is substantially U-shaped. I do not limit myselfto either or both of these particular forms, for obviously thegenerator-tube may have quite a number of different forms, all comingwithin thescope of my invention.

The operation of my device is as follows: The liquid hydrocarbon havingpassed into the passage 7 and vapor-tube 16 by opening the valve 6 bymeans of the hand-wheel 4, the heat from the mantle 2l causes vapor tobe generated within the tube 16, and this vapor is highly heated bypassing through the long and sinuous path formed by the vapor-tube. Thevapor passes nearly to the top of the mantle and down again, enteringthe casing 8 by means of the passage 9, thence passing upward throughthe passage or oriiice 10 to a point below and concentric with thetubular member 19, as indicated in Fig. 3. Within the orifice 10 thevapor encounters the flattened needle 11 and is obstructed upon bothsides thereof, issuing from the upper end of the orifice 10 andimmediately commingling with more or less air. The admixture of air andvapor thence passes upward through the tubular member 19 to the mantle21, causing combustion and maintaining the heat in the generator-tube16, so that the process is continuous.

IDO

sol

Ventilation is afforded by means of the holes 31a in the usual manner.

I nd that the fiat form of the needle 1l causes the admixture of vaporand air to be more thorough. In other words, this form of needle enablesmore oxygen to accompany the vapor as it proceeds through the gallery tothe mantle. The flattened needle is also self-cleaning.

As above explained, the opening 22 in the top of the mantle beingobstructed by the upper end of the vapor-tube 16 causes the hydrocarbonvapor to pass through the meshes of the mantle and to burn readily. Thespiral form 16a of the generator-tube, (shown in Fig. 5,) is preferablein cases where coal-oil is to be vaporized for the reason that this oilrequires a much higher degree of heat than gasolene in order to convertit into a dry vapor which will burn comparatively free from smell.

With my invention the mantle may be readily placed in position by evenan inexperienced person. To hang the mantle upon its support is often adelicate task and many mantles are destroyed while being placed inposition. With my device the danger of breaking the mantle from thiscause is reduced to a minimum. It will be noted further that with mydevice the mantle may be suspended in such a position as to be perfectlyconcentric with-the gallery and is therefore in a sense adjustable.

My generator-tube may be used in connection with any ordinary galleryused upon burners for city gas.

By means of my invention thorough combustion is assured, together withabsolute safety. No odor is produced. The heat is so intense that thevapor is very dry.

With my invention it is quite easy to place the mantle correctly inposition, as the normal position of the mantle is its position ofgreatest equilibrium and is such that the mantle is disposed directlyover the iiame. The savin g of mantles alone is a considerable item.With other mantle-supports it sometimes happens that the number brokenin mounting exceeds the number worn out by proper use. As my mantle isself-adjustable, little or no skill is required in placing it inposition. f

The lightness and simplicity of the generator render it easily andquickly heated, and the cooling eect of the vaporization prevents theheat from reaching the melting-point.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. An incandescent vapor-burner, comprising a casingprovided with an aperture, a second casing provided with a lug forengaging said aperture, thereby detachably securing said casingstogether, a generator-tube connected with both of said casings, meansfor admitting a hydrocarbon liquid to one of said casings, the other ofsaid `casings being provided with a vapor-jet orifice, a needlevalvearranged to control said oriiice, a mantle disposed within the path ofsaid vapor for heating said generator-tube, a mixing-tube andburner-cap, and means for admitting air to said mantle.

2. An incandescent vapor-burner, comprising a casing provided with anaperture, a second casing provided with a lug for engaging said apertureand locking said casings together, a substantially U-shapedgeneratortube connected at its ends with said casings respeetively,amantle hung directly upon said generator-tube, a mixing-tube and aburnercap, a needle-valve mounted upon one of said casings fordischarging hydrocarbon vapors into said mantle, mechanism for admittinghydrocarbon liquid to the other of said casings, and means for admittingair to said mantle.

3. An incandescent vapor-burner, comprising a casing provided with anaperture and free to serve as a support, a second casing provided with alug for engaging said aperture, thereby detachably securing said casingstogether, a generator-tube connected with each of said casings, a mantledisposed adjacent to said generator-tube, means for admitting ahydrocarbon liquid to one of said casings, a valve connected with otherof said casings for discharging hydrocarbon vapor, said valve having theform of a flattened needle :fitted into an aperture within saidlastmentioned casing, and means for admitting air to said mantle.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
